A large percentage of the population experiences some type of trauma in their lifetime. One extreme reaction to trauma exposure is the elicitation of a personality disorder, specifically Borderline Personality Disorder (BPD).

The focus of this paper is three-fold. First, it compares two treatment approaches: Dialectical Behavior Therapy (DBT) and Traumatic Incident Reduction (TIR). These are different in technique and philosophy when regarding the processing of traumatic events. Second, it reviews the evidence for co-morbidity (simultaneous occurrence) between BPD and PTSD. Finally, this paper will propose a strategic plan for the most effective treatment for individuals with BPD and PTSD symptoms.
